术语 | communication bit stuffing |
释义 | communication bit stuffing 通信填充位 A technique used to achieve data transparency. To ensure that a flag character does not appear in data field, a zero-bit is inserted wherever five one-bit appear in a row. When the receiver detects five ones followed by a zero-bit it removes or deletes the zero-bit. If it receives six ones and a zero, it is a legal flag character that indicates end-of-message. 为使数据具有“透明性”而采用的一种技术。为保证标志符不在数据区内出现,可在每5个“1”后插入一个“0”。当接收器检测到5个“1”后跟着 一个“0”,就把该“0”位删除掉;如检测到6个“1”后跟着一个“0”,则把它作为合法的电文结束标志符对待。 |
